If we weren't exchanging messages over email you'd see me doing a little victory dance right now! Which, not too surprisingly, makes me glad we're exchanging messages over email.
I was using a version of JBoss pulled from CVS in the last day or two, but was using examples and docs that applied to the alpha release. Right before your email I had decided that JBoss was completely ignoring everything I had in my jbosscmp-jdbc.xml file - which it was, because I was using the old style where <foreign-key-mapping> and <table-mapping> wrapped the roles. Who would have thought to go look at the DTD? I mean, it's only the exact description of how I should be formatting the config file. Sigh... Thanks for kicking me in the right direction, everything works wonderfully now.

Problem This is definitely a job for the jbosscmp-jdbc.xml file. What version of JBoss are you using? The structure of this file changed between the alpha and the beta. The xml for the classic Order-LineItem in JBoss 3.0 beta follows: <ejb-relation> <ejb-relation-name>Order-LineItem</ejb-relation-name> <foreign-key-mapping/> <ejb-relationship-role> <ejb-relationship-role-name>order.getLineitems()</ejb-relationship-role-name > <key-fields> <key-field> <field-name>ordernumber</field-name> <column-name>ORDER_NUMBER</column-name> </key-field> </key-fields> </ejb-relationship-role> <ejb-relationship-role> <ejb-relationship-role-name>lineitem.getOrder()</ejb-relationship-role-name> <key-fields/> </ejb-relationship-role> </ejb-relation> As you can see the roles have been moved out of the foreign-key-mapping element and keys are always specified in terms of the current entity which is backwards from the old foreign key mapping but exactly the same as the table-mapping. Read the dtd for more info. -dain Robertson, Jason wrote: > I have two prebuilt tables that look like this: > > mysql> select * from organizationtype; > +-------+---------------+ > | name | description | > +-------+---------------+ > | type1 | orgtype-desc1 | > | type2 | orgtype-desc2 | > +-------+---------------+ > 2 rows in set (0.00 sec) > > mysql> select * from role; > +-------+-------------+-------------+ > | name | description | orgTypeName | > +-------+-------------+-------------+ > | role1 | role-desc1 | type1 | > | role2 | role-desc2 | type1 | > | role3 | role-desc3 | type1 | > | role4 | role-desc4 | type2 | > +-------+-------------+-------------+ > 4 rows in set (0.00 sec) > > Where role->orgTypeName is a foreign key to organizationtype->name. > > I was an accessor RoleEntity.getOrganizationType() to return an > OrganizationTypeEntity.
